Application filed June 22. 1906- Serial No. 322.901-

T 0 all whom it may concern:

Be it known that I, CLAUDE SIN'rz, a citizen of the United States, residing at Grand Rapids, in the county of Kent and State of Michigan, have invented certain new and useful Improvements in Reversible Propeller- Wheels; and I do hereby declare the following to be a full, clear, and exact description of the in the art to which it appertains to make and use the same. v

My invention relates to improvement in reversible propeller wheels, and its object is to provide a strong, compact structure; to provide improved means for holding, shiftthat will present but little obstruction in passing through the water,,and that will not readily become fouled; to provide a wheel thatwvill be easily shifted when inoperation; to provide a device that is easily inanu factured, and thatnnay be readily assembled and dis-assembled; and to provide the hereinafter more fully described and particularly pointed out in the claims, reference being had to the accompanying drawings, inwhich:

Figure 1. is a transverse section on the l nalsection of the same; Rig. 3. arear end elevation of the case orshell; Fig. 4. a planview of the hub complete; and, Fig. 5. a transverse section'of the same on the line 55 of Figs. 2 and 4.

Like numbers refer-to'like partsin' all of the figures. 1 represents the driving shaft rotated by any convenient motor ;v2 is a sleeve slidable on the "shaft and manually adjusted in the usual way y anyconvenient means; 3 is the case or she l of thehulo' provided with internal key-waysfl l and also having .elongated radial 0 enings 5 corresponding to the number of bFades ofthe wheel, three being herein shown. v

Each opening is surrounded with a plane a conical cap 7 which also closes the rear end of the shell. This cap is secured in place by screws 8 having their heads recessed i intdthe cap. 9 is a triangular head fixed'on the having 9 are radial studs 10 projecting within the openings 5, on'which studs the blades are journaled by means ofinte ral tubular shanks each having an inner an e 14 en- I gaging the inner surface of the she I to hold the blade in place on the stud. Said shanks are also provided with radial arms 16 to rotate and adjust the blades upon the stud 10. Each arm is slotted at the outer end, and inserted in the slot a pin15 secured in the shell 3 whereby as the shell is moved longitudinally of the shaft the. blades are rotated on the studs andadjus'ted to drive either forward or backward or in intermediate position. ,1 I To adjust the shell longitudinally of the shaft and head, the same is connected and secured-to the sleeve 2 by means of a bushing 18 interposed between the shell and sleeve and secured to each by screw threads. I

In the head 9 and op osite the end of the shaft 1, are splines or eys 11 ads. ted to traverse the key-ways 4 as the she is adjusted longitudinally of-the shaft.- These splines thus adjustably connect head and gagement of the shank with the si eof the slot 5 in the head.

It will be noted that the hub entire consists of a symmetrical pear shaped structure a flattened portion opposite each blade and that the flanges 13 engaging said portions are each a section of a globe having a radius corresponding to the radius of the shell whereby a smooth and symmetrical bod. is provided adapted to pass freely through the water longitudinally, and to rotate rapidly therein, with but little'resistance, and

that there are practicall no projections 'to Whichgrass or weeds cancome attached. v

It will also be observedthat by removal of j I the cap 7,- the. shell and openings ,5 are all o en rearwardly and that the shell can he s id forward on the shaft and the parts withinthe s'ame readily dis-assembled; or assembled. SAlso by. the use of the sleeve 18, the forwai d end of the shell 3 may be bored and the key-ways cut therein with facility and convenience. Furthermore the engagement of the shell with the shank of the blade being ward on the shaft. a;

opposite the end of the stud, there will be no cramping or binding of the same to prevent or hinder shifting the device manually when in operation.

, Obviously the connection between the shaft and shell may be omitted and the blades driven quite effectively by the studs only. It will also be noted that no screws or keys are used to hold the blades in place and that they can always be easily removed or replaced by merely removing thev screws 8 .that hold the cap-and sliding the shell for- What I claim is: a 1. A propeller wheel, comprising a head adapted to be secured to a shaft, radial studs on the head, a shell'surrou'nding the head, radial slots in the shell opposite the studs, blades having tubular shanks rotative on the studs and adapted to traverse the slots, flanges on'the shanks engaging and travers-' ing the inner surface of the shell, and means for connecting the, shell and shanks to rotate and adjust the blades on the studs.-

2. A propeller Wheel, comprising a head ada ted to be attached to a shaft, radial stu s on the head, a shell liaving radial slots opposite said studs, said shell and slotsbeing open at the rear, a conical cap detachably secured to the rear of the shell to close the shell and slots, blades having tubular shanks rotative on the studs, flanges on the shanks engagin and traversing the interior of the shell an means for connecting the shell and shanks to adjust and hold the blades.

3. A propeller wheel, comprising a head adapted to be fixed on the end of a shaft, radial studs on the head, a shell surrounding the head and longitudinally adjustable, said shell having slots opposite the respective studs, blades having tubular shanks journaled on the studs and traversing the slots, flanges on the shanks engaging and traversing the inner surface of the shell, slotted arms on the shanks and pins fixed in the shell and engaging the slots of the arms.

4. A pro eller wheel, comprising a head adapted to e fixed on a shaft, radial studs on the head, a tubular shell surrounding the head and having radial slots opposite the studs, means for slidably connecting the head and shell,.blades having tubular shanks journaled on the studs and traversing the slots, flanges on the shanks and engaging the inner surface of the shell, and a detachable cap to close or open the rear end of the shell and slots therein.

5. A propeller Wheel, comprising a substantially pear-sha ed shell having radial slots, said shell an slots being open at the rear end, a detachable conical cap to close the shell and slots, a head within the shell and slidably connected thereto, radial studs on'the' head and projecting within the said slots, blades having tubular shanks journalcd on the studs and traversing the slots, flanges on the shanks engaging and traversing the inner surface of the shell and means for connecting the shell, and shanks to adjust and hold the blades.

6. A propeller Wheel, comprising a substantially pear-shaped shell having radial slots and plane surfaces surrounding the slots, a head Within said shell, means for slidably connecting the head and shell,

blades having shanks inserted in said slots and traversing the same, means for rotatively connecting the shanks and the head, inner and outer flanges on the shanks and engaging the respective inner and outer surfaces of the shell, and means for connecting the shell and shanks to rotatively adjust the blades.

7. A propeller wheel, comprising a shell I open at the rear and having radial slots also 0 en at the rear, a detachable conical cap to c ose said" shell and slots, a, head Within said sleeve, a shell attached to the bushing and having internal key-ways and radial slots, at head fixed on the end of the shaft, splines in the head and traversing the key-ways, radial studs on the head, blades having tubular shanks j ournaled on the studs, flanges on the shanks and engaging the inner surfaceof the shell, a detachable conical cap to close the rear of the shell and slots and means for connecting the shanks and shell to adjust and hold the, blades.

9. A propeller wheel com rising a head adapted to be attached to a s aft and driven thereby, blades mounted on the head and rotative on radial axes, means for .rotating 1 and adjusting the blades, a. shell surrounding the head and longitudinally adjustable thereon, means for slidably connecting the shalt and shell to positively rotate the shell inde endent of the blades, and means for I slida ly connecting the shell and the blades, whereby the blades are driven by the shell as well as by the head.- a
